- version 3.17
- check: --init-csum-tree acutally does something useful, rebuilds the whole
csum tree
- /dev scanning for btrfs devices is gone
- /proc/partitions scanning is gone, blkid is used exclusively
- new subcommand subvolume sync
- filesystem df: new options to set unit format
- convert: allow to copy label from the origin, or specify a new one

Subject: [PATCH 11/42] btrfs-progs: check if we can't get info from ioctls due
|
|
to permissions
|
|
|
|
The TREE_SEARCH ioctl is root-only, FS_INFO will be available for
|
|
non-root users with an updated kernel, let the user know.
